第一次发帖。所以我必须在一个看起来像这样的元素中格式化一些文本

<div class="entry-time">
  2012-05-30T20:11:06+00:00 
</div>

我正在尝试使用moment.js将其格式化为更具可读性的内容。我只能从前端使用 javascript 执行此操作。我写了一个看起来像这样的函数。

$(document).ready(function() {
    function formatDate(date) {
        formattedDate = date.text();
        var d = moment(formattedDate, "YYYY-MM-DDTHH:mm:ss");
        $(date).html( d.format("dddd, MMMM Do YYYY, h:mm:ss a"));
    };

    formatDate($('.entry-date'));
});

如果有一个元素，则此方法有效，但当有多个元素时，它将所有内容格式化为一个日期。我知道这与 jQuery 拉入一组元素有关，但我不知道如何使用 entry-date 类对每个元素执行我所做的操作。

任何人都可以帮忙吗？先感谢您。

At the heart of what's wrong is that the jQuery .text() method gets "the combined text contents of each element in the set of matched elements, including their descendants" (api.jquery.com/text) rather than iterating over the set of elements as you intend.

Something like this should work, passing a function into the jQuery .html() setter method:

$(".entry-date").html(function(index, value) {
    return moment(value, "YYYY-MM-DDTHH:mm:ss").format("dddd, MMMM Do YYYY, h:mm:ss a");
});

您需要使用 jquery 的 .each 方法遍历每个匹配项：

$(date).each(function(){  Format date here  });

这将进入您现在现有的函数 formatDate。

You will want to loop through the elements passed to the function. This could be done with a $.each() in jQuery. Here's a quick example:

http://jsfiddle.net/n1ck/QQYq2/1/

$(function(){
    function formatDate(dates) {
        dates.each(function(){
            //get date
            formattedDate = $(this).text();

            //format it
            var d = moment(formattedDate, "YYYY-MM-DDTHH:mm:ss");

            //replace it
            $(this).html(d.format("dddd, MMMM Do YYYY, h:mm:ss a"));
        });
    };

 formatDate($('.entry-time'));
});

Based on your current code you can modify your formatDate function like this

 $(document).ready(function() {
    function formatDate(date) {
      date.each(function(){
        var formattedDate = $(this).text();
        var d = moment(formattedDate, "YYYY-MM-DDTHH:mm:ss");
        $(this).html( d.format("dddd, MMMM Do YYYY, h:mm:ss a"));

      });
  };

 formatDate($('.entry-time'));
});

And you actual class name is entry-time but you are calling like formatDate($('.entry-date')); which will get nothing as the class entry-date doesn't exist.

Working Fiddle​</p>

You have to use each because your selector is a class(since you used '.') which can be used with multiple DOM's as well..so may be your jquery thing is returning an array which is to be traversed using each.

$('.entry-date').each(function(){
   formatDate($(this).val());//if it is a text box
});

OR

$('.entry-date').each(function(){
   formatDate($(this).text());//if it is a label
});
